Keystone Montessori School 55 Middlesex Street, Chelmsford, MA 01863

"My two daughters are in the children’s house for several years. The younger one joined last year and grows a lot in Keystone. The teachers are amazing, all kind of activities in the classroom are amazing! Even my older one has already graduated for 2 years, she always mentioned she missed the time in Keystone and Mrs Vajjhala was her favorite teacher!"

"Fabulous head teachers in the Children’s House program and a wonderful curriculum to learn life skills, independence and a love of learning in academics and beyond. The amount of days off and cost are challenging as working parents, but we believe that the net gain is positive for our 2 children who attend Keystone."

"Our son has been in Keystone since he as 14 months old. The staff in the Beginners program had such a big impact on his development. He has been consistently meeting his milestones early. He is happy and excited to learn. I would recommend this to any parent who is looking for a program that will support learning and development from an early age. Far superior to the typical child care you can get from most similarly priced programs."

"Keystone Montessori is an excellent school for kids with a variety of different age groups. Their teaching is geared toward both academic and social learning, and encourages curiosity and independence. They have amazing teachers who are very accommodating and closely work with parents. The school administration is always helpful at every level. We like the diverse learning environment which is a great opportunity for kids to be exposed of early on. We are also grateful for Keystone’s pandemic policies, diligently following safety protocols, and keeping our kids safe during these difficult times. We strongly recommend Keystone Montessori to all parents."

"Outstanding teachers, nurturing learning environment and caring staff are the hallmarks of Keystone Montessori school. Our 4-yr daughter thrives at the school, she can already write and is learning to read at rate that is astounding to us. There was a huge difference in her interest, focus and performance once we moved her to Keystone. I recently attended a Parent day to observe my daughter in the classroom and I was most impressed with the multisensory math materials, which wer carefully laid out from simple to complex, offering a concrete representation of abstract mathematical concepts such as simple operations, area, volume, and measurement including the decimal system - for my 4-yr old! :-) I really feel fortunate and confident that my daughter is getting an outstanding early education and head-start in academic learning. I would recommend any parent wanting their child to learn in an nurturing environment that places an emphasis on independence, freedom within limits, and respect for their child’s natural psychological, physical, and social development to give Keystone a try, as it's one of, if not the best Montessori school in the greater-Boston area."
